Sorry, I was unclear. I want it re-exported from Data.Tuple, so I don't need to import ghc-prim:GHC.Tuple. I proposed this on the libraries list last year, and the two people who responded agreed.

The GHC.Tuple modules (from ghc-prim) are identical in the HEAD and ghc-9.2
branches. With HEAD I see:
$ ghci
GHCi, version 9.3.20210809: https://www.haskell.org/ghc/ :? for help
Loaded GHCi configuration from /usr/home/viktor/.ghc/ghci.conf
